Glass Break Detector

Ademco's 2520 is simply the most advanced glassbreak detector available today. Our mission was to develop the ultimate level of performance in vital areas of glassbreak protection.

The 2520 hears the acoustic shock wave and the unique multi frequency audio signature of glass breaking; then processes the signal digitally with computer speed and accuracy to detect the sounds of an actual glassbreak event. The microprocessor’s algorithm identifies multiple variations of the glassbreak signal data in both unique time and frequency domains. In short; it compares the sound it hears to the signature analysis of breaking glass...and ignores extraneous noises. Since the detector is analyzing wave shape or signature... not amplitude, it will detect breakage through curtains, drapes, windows, blinds and from glass fitted with a sun tint coating.

• Mount the 2520 just about anywhere...on any wall or ceiling.
• Protects all types of glass; plate, laminated, tempered or wired.
• May be mounted on the same wall as glass surface.
• No sensitivity adjustments needed.
• No test mode jumpers to move... test period automatically times out after 5 minutes.
• Uses computer speed and accuracy to monitor all sounds and rejects those that don’t match the microprocessor algorithm for glassbreak signature.
• SMD (surface mount device) component design ensures unsurpassed RFI protection.
